Title: Laminated sheet materials
Inventor: LORD FRANK WHITLEY
IPC: B32B27/00
Filed: 1965-02-03
Abstract: 1,128,611. Laminates and laminating. IMPERIAL CHEMICAL INDUSTRIES Ltd. 21 Jan., 1966 [3 Feb., 1965], No. 4681/65. Heading B5N. A process for the manufacture of laminated sheet materials comprises applying a polyurethane coating composition to a surface of a reinforcing material, the coating then being dried before applying to the said coated surface a sheet or block of cellular polymeric material, the latter then being compressed whilst being held at a temperature of 140-200‹ C., so that after removal of the compressing force the cellular polymeric material remains substantially in its compressed state. As described the reinforcing material is paper; textile material, e.g. woven cotton or synthetic fibre fabrics made from e.g. polyhexamethylene adipamide or polyethylene terephthalate; rubber, synthetic rubber; sheets of synthetic plastics materials; or metallic sheets e.g. of aluminium. The cellular polymeric material may be rigid, semi-rigid, or flexible before compression and preferably has a preponderance of open cells. The material may be foamed cellular polyurethane, polystyrene, polypropylene, polyepoxide, polyamide, polyester, polyvinyl, or polycarbonate material. The polyurethane coating may be produced from reaction mixtures containing organic polyisocyanates, and polyhydroxy compounds and normally contains a solvent, e.g. hydrocarbons, chlorinated hydrocarbons, ethers, and ketones, or mixtures thereof. The coating is applied to the reinforcing material by brushing, spraying, or dipping, and is then dried at atmospheric or elevated temperatures. The cellular polymeric material is then applied to the coated surface and the assembly is preferably pre-heated before heat and pressure is applied by a press or rollers. The cellular material is preferably compressed to 2 to 20% of its original thickness. If desired the laminates may contain many layers, in which case the reinforcing material is coated on all surfaces which are to contact the cellular material, and in an example a three layer sandwich is produced. In one embodiment the laminate has thermal insulating properties, and in another it can be used as a substitute for natural leather.

Title: Calibrating heading systems
IPC: G01C25/00
Filed: 1961-02-08
Abstract: 920,678. Electric indicating systems. MINISTER OF NATIONAL DEFENCE OF HER MAJESTY'S CANADIAN GOVERNMENT. Feb. 8, 1961 [Feb. 15, 1960], No. 4702/61. Class 40(1). An aircraft heading system is calibrated by comparing a signal representing the assumed heading with a reference signal derived from a sextant, the difference being used to drive the sextant heading ring, the arrangement being that if the bearing of the celestial body does not coincide with the zero index of the heading ring a calibrating signal is applied to the heading system so as to alter the output of this system until it does. As shown (Fig. 1) the assumed heading of the craft derived from the magnetic or gyro compass is applied as one input to a differential synchro 31. The azimuth bearing of the celestial body is set in as another input to the same synchro by handle 20. The difference signal, if any, is applied through closed switch 25 to a synchro control transformer 37 and amplifier 38 to a servomotor 40 which drives the sextant heading ring and the synchro transformer 37 to balance the loop. The operator now positions the sextant so as to observe the cross-wires against the zero index. He should now see the celestial body in the same position. If he does not he closes switch 28a or 28b to transmit a calibrating signal to the heading device. This device then feeds a different signal to differential servo 31 to again drive the heading ring. Switch 28 is opened when they coincide. If a series of readings is to be taken the rate of variation of the azimuth of the celestial body may be set in by handle 22 which adjusts a potentiometer 48 controlling the speed of a rate motor 35. This motor feeds a constantly changing si al into the differential synchro 31 during the period of the observations. A clutch 33 slips when the azimuth is applied manually to handle 20 so that the manual setting is not applied to the azimuth rate motor.

Title: Improvements in or relating to a method of, and apparatus for continuously preparingsynthetic plastics and the like materials
IPC: B01F27/73
Filed: 1963-02-06
Abstract: 987,030. Mixing synthetic plastics. HENSCHEL-WERKE A.G. Feb. 6, 1963 [Feb. 9, 1962], No. 4856/63. Heading B1C. Apparatus for continuously preparing in granular form synthetic plastics and the like comprises a horizontal tubular container with rotatable axial shaft carrying mixing tools having the general form of swash-plates or wobble-spiders. As shown, each swash-plate is divided into three segments, the two segments 5 being arranged forwardly of the normal to the shaft and tending to sweep the material forward, and the third segment 7 being arranged behind the normal and tending to sweep material backwards, the forward effect being dominant. The material is thus given reciprocating and rotary motions. The blades may be fixedly attached to the shaft or detachably by bayonet couplings and there are internal baffles (not depicted) in the container adjustable from outside it. The peripheral speed of the mixing tools is 7-9 m./sec. All the mixing tools have the same inclination to the shaft but some may be in different planes as at 6. The materials are introduced at 9 while an additive may be introduced at 11 and pass along the hollow shaft 2 to an aperture 12 preferably arranged in the first fifth of the mixing system, where it is thrown out by centrifugal force. The apparatus may be pivoted at 13 so that it may be inclined to assist the passage of materials. It may be externally heated or cooled. The outlet aperture may be adjusted by a flap valve controlled mechanically, magnetically, electrically, pneumatically, or hydraulically by the motor or by a governor in dependence on the power absorbed by the motor to maintain the consistency of the mixture constant.

Title: Storage arrangements
IPC: G06F17/30
Filed: 1976-02-09
Abstract: 1533325 Associative storage system SIEMENS AG 9 Feb 1976 [10 Feb 1975] 04912/76 Heading G4A An associative storage system includes an addressable store ASP1 to store tags and associated data items, a comparator to compare tags read from the store with search words, and a unit RES arranged to divide the store into independently searchable zones. The unit RES derives from a tag or a part of a tag a group of 1-bits FRAG and, in response to control data BGR pertaining to the zones, selects from among those l-bits and a group of l-bits BAD defining a zone address, a group of l-bits SAB which, in conjunction with the contents of an extension counter EZ, which are incremented whenever an addressed storage location is occupied, are used to form an l-bit store address into which the tag and its associated data item are loaded. The store may be as described in Specification 1,533,326 or 1,475,785. The extension counter enables the zones to be extended as necessary during the loading of data. Using the store of Specification 1,533,326 part of a tag in register REG is selected by a variable width mask MASK and fed via switch MOD, position m2 into l-bit register FRAG. Registers BGR and BAD are loaded respectively with zone control data and a zone address and, in response to the control data, a variably positioned l-bit mask SAB selects a group of l contiguous bits from FRAG and BAD. The resulting I bits are used as described in Specification 1,533,326 to select a store address into which the tag and its associated data item may be loaded. The extension counter, together with the book keeping store are also used as in Specification 1,533,326 to extend the zone as required when a new tag selects an occupied location. Searching the store for a given tag is also as in Specification 1,533,326 but using the zone control data as above to derive the first address. The extension counter is used as necessary to provide further address until the tag read out matches the search tag. The system operates in a similar manner with switch MOD in positions m1 and m3 except that respectively the tag is extended by MASK and the resulting bit group is applied to a converter (Figs. 6 and 7, not shown) which reduces the number of bits to l, and the tag is fed to a code compressor from which the l-bits are derived. Using the store described in Specification number 1,475,785 the l-bits selected by the mask SAB above are fed to the code converters associated with individual storage banks which, in conjunction with the extension counter, form store addresses as described in the earlier Specification.

Abstract: 1,100,718. Semi-conductor devices; printed circuits. HUGHES AIRCRAFT CO. 4 Feb.. 1966 [1 March, 1965], No. 5010/66. Headings H1K and HIR. In a semi-conductor device having an electrode contacting the semi-conductor body through an aperture in an insulating layer, part of the electrode is thickened by masking and electroplating. A plurality of transistors simultaneously produced in a silicon wafer (4) by the planar technique, and having a glass or silicon oxide layer (10) which may be thickened by pyrolytic decomposition, are contacted by etching base and emitter contact windows in layer (10), vapour depositing a silver layer over the surfaces, and masking and etching to form the required electrode pattern which includes pads (15, 16) overlying layer (10) and connected by strips (12, 14) to base and emitter contact areas (8<SP>1</SP>, 9<SP>1</SP>) respectively, Fig. 4 (not shown). The masking layer is removed and a thin silver layer (17) is vapour deposited over the whole surface, Fig. 6 (not shown). A photo-resist layer (18) is deposited and processed to expose parts of layer (17) overlying contact pads (15, 16), Fig. 7 (not shown). An electrical connection (17<SP>1</SP>) is applied to layer 17 and the wafer is electroplated, using layer 17 as a plating electrode, to form silver contact " bumps " 19, 20, Fig. 8. Similar " bumps " (6<SP>111</SP>) may be simultaneously produced on collector contacts (6<SP>1</SP>) applied to the top face of the wafer, Fig. 10 (not shown). Photo-resist layer (18) and silver layer (17), apart from the areas beneath the " bumps," are removed by etching or by using a high velocity water spray, and the wafer is then diced. The electrode pattern may alternatively be produced from chromium graded to aluminium graded to silver. In an alternative embodiment the electrode pattern includes a grid which interconnects all the electrode regions to provide the electroplating electrode. After forming the " bumps " the grid may be removed or cut by etching or scribing or by the dicing of the wafer. The surface of the wafer, apart from the contact " bumps," may be masked with a permanent or temporary layer of insulating or non-metallic material and the " bumps " coated with solder by dipping the surface in a solder bath. The invention may also be applied to diodes and other devices and the wafer may also be germanium or glass. Various electrode geometries are illustrated, Figs. 10, 11 and 12 (not shown).
